1·Conclusion: The analysis method for irone using GC-MS and GC was high - efficient, precise. The analysis t...

结论：采用气相色谱-质谱法及气相色谱法分析鸢尾酮，简便、高效、准确、分析时间适中。

2·Results: The three isomers of irone was speculated according to the MS _ splitting _decomposition law. Irone in two passel of Iris tectorum material was determinated.

结果：依据质谱裂解规律初步鉴定三种鸢尾酮的异构体，测定了两批原料中鸢尾酮的含量。
